IMPROVEMENT IN MOWING-MACHINES.

Specification forming partof Letters Patent No. 20,164, dated May 4,1858.

To all whom it may concern:

Be it known that I, HENRY MARcELLUs, of Amsterdam, in the county ofMontgomery and State of New York, have invented a new and ImprovedMowing-Machine; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theannexed drawings, making a part of this specilication, in which- Figurel is a side sectional elevation ot" my improvement, taken in the line a'm, Fig. 3. Fig. 2 is back view of the same. Fig. 3 is a plan or top viewof the same.

l Similar letters 'of reference indicate corresponding parts in theseveral ligures.

This invention consists in. a novel way of attaching the main frame ofthemachine to `its axle, as hereinafter fully shown and described,whereby the sickle is allowed to conform tothe inequalities of theground withv out at all affecting the perfect operation of thedriving-gear, and the machine as a whole rendered extremely simple andeffective.

To enable those skilled in the art to fully understand and construct myinvention,l will proceed to describe it.

A represents an axle. B Bare wheels tted thereon. The wheel B is littedloosely on-the axle, but the wheel B isattached permanently to it.

C is a sleeve or collar, which is placed loosely on the axle A, andadjoining the wheel l. This sleeve or collar has an arm or projection,a, attached to its front part at right angles.

D is the main frame of the machine, which is formed of a cast-metalplate, having the linger-bar E rigidly attached to its back end, atright angles with it., as shown in Fig. 3. 'lhe front end of the mainframe D has a vertical ledge, b,'i'ormed on it, through which a journal,c, at the front end of the arm or projection a, passes loosely, and ajournal, d, at the back end ofthe sleeve or colla-r C, and in linewithjournal c, passes into an upright, c, attached to the main frame.(See Fig. l.) By this means the main frame is attached to the axle A,and it will be seen that a universal-joint connection is obtained-thatis to say, the platform is allowed to vibrate or move vertically in aplane at right angles with the axle A, and also in a plane parallel ornearly parallel with it. j

F is a bevel-wheel, which is placed on the axle A, and securedpermanently to it, adjoining the end ofthe lsleeve or collar C.

This bevel-wheel gears into a bevel-pinion, f, which is placedon ashaft, G, one end of which has its bearing in the upright, e. Theopposite end of the shaft Gr has its bearingin an upright, g, which isattached t0 the main frame D at its back part. The back end of the shaftG has a toothed wheel, h, on it, said wheel gearing into a pinion, i,which is placed on a shaft, H, parallel with the shaft G, and having itsbearings in the same uprights, e g. The back end of the shaft H hasac'rankpulley, l, placed on` it, said crank-pulley having aconnecting-rod, J, attached to it, which connecting-rod drives thesckleK, which is placed on the linger-bar E. y

P is the drivers seat, which is attached to an upright, Q, at the frontend of the main frame, and at one side ot' it, as shown in Fig. 2. t

From the above description it will be seen that as the machine is drawnalong the iinger-bar, and consequently the sickle, will rise and fall toconform to the inequalities of the surface ot' the ground, thelinger-bar being allowed to rest on the ground, the linger and mainframe working or moving together, as they are rigidly connected, and themovenection ot' the main frame to the axle A. It will also be seen thatthe driving-gear F f ot' the main frame, as the axis of the pinion j isat all times in a radial position relatively with the wheel F.

By means of the plate L, lever N, and bar O the finger-bar and sicklemay be raised and supported at the proper height, the two caster-wheelsM. M retaining the linger-bar and main frame in proper positions.

`By this improvement the machine is rendered extremely simple, it beingcomposed of but very few parts, and none that are liable to get out ofrepair.

Having thus described my invention, what l claim as new, and desire tosecure hy Letters' Patent, is^

Attaching the main frame D 'of the machine to the axle A by connectingthe frame, by means ot' journals c d, to the sleeve or col lar C, whichis placed loosely on the axle A, substantially as and for the purposeset forth.
